Operator Panel or Change object properties

I’m watching a tutorial and in the tutorial from CGCookie he says to press f6 to bring up properties for the item like vertices radius and depth. I can’t find where to change properties of newly created objects like this.

Does not F6 work for you? If not, if you look on the toolshelf (T) at the bottom, you should see the setting for newly created objects.

I got it to work thanks, the object was old. I had to do it as soon as the object was created.
